Excerpt from Madame Bovary - Gustave Flaubert
“As for Emma, she never questioned herself to find out if she loved him. Love, she believed, must come suddenly, with great thunderclaps and bolts of lightning, —a hurricane from heaven that drops down on your life, overturns it, tears away your will like a leaf, and carries your whole heart with it off into the abyss. She did not know that the rain forms lakes on the terraces of houses when the drainpipes are blocked, and thus she would have lived on feeling quite safe, had she not suddenly discovered a crack in the wall.”
